Load Ring bolted - VWBG

Product enquiry

360° swivelling/180° pivoting – with a ball bearing

Complies with the machinery directives 2006/42/EG

Suitable for all loads which swivel and tilt. Can be loaded in all directions with a 4 : 1 design factor.

Swiveling under full load is permissible provided the inclination angle is not perpendicular to the screw - in direction.

Not suitable for permanent swiveling under full load. Can also be supplied with variable (vario) thread lengths. Easy assembly due to the single threaded tapping. High tensile, inspected suspension ring according to EN 1677-4. The surface is both pink powder coated and zinc plated. Patent 4336779-VARIO.

Choose the attachment points in such a way that the introduced forces are accomodated by the work piece without being deformed. Make sure the bolting surface is plain. Ensure an appropriate bore depth to facilitate an optimal sitting of the engaging surface. Work piece material, at least 1.0037 (St 37).

For light metals, nonferrous heavy metals and grey cast iron, the thread type allocation must be done in such a way that, the WLL of the thread type fulfils the requirements of the respective work piece.

Available for working load limits from 6 000kg to 40 000kg.

RUD Lifting Point

Owing to the presence of the ball bearing, in case of a single transportation procedure, fastening with a flat wrench according to DIN 895 or DIN 894 without using an extension is enough. Without a washer, the seat - engaging surface of the VWBG-V (D) must completely and evenly lie onto the surface of the work piece. Is the VWBG-V to be permanently loaded, it must be tightened with a torque of 10 Nm.

When impact loaded or operated in environments with skewing and vibrations, unintentional loosening can happen, especially if through bolts with nuts are used. Securing possibilities: Use of a liquid thread securing medium eg. Loctite ( follow the manufacturer´s recomendations) or positive bolt securing for example using a castellated nut with a split pin, counter nut etc.

The VWBG-V is not suitable for permanent swiveling under full load

For heavy loads which have to be turned and swivelled.

  • With ball bearings. Swivels under full load.
  • Not suitable for permanent swivelling under full load, especially in 90° direction.
  • Loadable in any direction. Safety factor 4 : 1.
  • Suspension ring manufactured acc. EN 1677-4 grade 80 (100 % proof loaded).
  • S = max. allowed gap, see hints for Installation page 39.
  • VWBG: Wear marks in the main load directions 45°, 60° and 90°.

Safety notice:
Please provide plain bolting surface. The countersunk for the thread should be: thread diameter plus 4 mm (0,15 inch). The base material of the workpiece must be capable to withstand the occurring lifting forces. Minimum required material = ST 37 (1.0037).
